As AI learns, it evolves and changes its output. In this sense, it differs radically from conventional medical devices and pharmaceuticals, which are required to deliver stable performance and effects, so the ethical issues it entails are complex. In clinical practice, physicians must take the greatest care to avoid excessive reliance on AI in supporting clinical decisions, lest they lose sight of their essential mission as physicians. AI also raises many issues for those receiving medical care, including the handling of personal information and the role of patients as users. Now is the time to discuss the kind of medical care we should aim to deliver by leveraging new technologies.
